Diagnostic Kit for Hepatitis C Virus Antibody (Fluorescence Immunochromatographic Assay)is a fluorescence immunochromatographic assay for the quantitative detection of HCV antibody in human serum or plasma,which is important auxiliary diagnostic value for infection with hepatitis C.All positive sample must be confirmed by other methodologies. This test is intended for healthcare professional use only
1.Lay aside all reagents and samples to room temperature.
2.Open the Portable Immune Analyzer(WIZ-A101), enter the account password login according to the operation method of the instrument, and enter the detection interface.
3.Scan the dentification code to confirm the test item.
4.Take out the test card from the foil bag.
5.Insert the test card into the card slot, scan the QR code, and determine the test item.
6.Add 20μL serum or plasma sample to sample diluent, and mix well..
7.Add 80μL sample solution to sample well of the card.
8.Click the “standard test” button, after 15 minutes, the instrument will automatically detect the test card, it can read the results from the display screen of the instrument, and record/print the test results.
9.Refer to the instruction of Portable Immune Analyzer(WIZ-A101).
Hepatitis C virus (HCV) is an envelope, single stranded positive sense RNA (9.5 kb) virus belonging to the family of Flaviviridae. Six major genotypes and series of subtypes of HCV have been identified. Isolated in 1989, HCV is now recognized as the major cause for transfusion associated non-A, non-B hepatitis. The disease is characterized with acute and chronic form. More than 50% of the infected individuals develop severe, life threatening chronic hepatitis with liver cirrhosis and hepatocellular carcinomas. Since the introduction in 1990 of anti-HCV screening of blood donations, the incidence of this infection in transfusion recipients has been significantly reduced. Clinical studies show that significant amount of HCV infected individuals develop antibodies to NS5 non-structural protein of the virus. For this, the tests include antigens from the NS5 region of the viral genome in addition to NS3 (c200), NS4 (c200) and the Core (c22).
PRINCIPLE OF THE PROCEDURE
The membrane of the test device is coated with HCV antigen on the test region and goat anti rabbit IgG antibody on the control region. Lable pad are coated by fluorescence labeled HCV antigen and rabbit IgG in advance. When testing positive sample, the HCV antibody in sample combine with fluorescence labeled HCV antigen, and form immune mixture. Under the action of the immunochromatography, the complex flow in the direction of absorbent paper, when complex passed the test region, it combined with HCV antigen coating antigen, forms new complex.HCV antibody level is positively correlated with fluorescence signal, and the concentration of HCV antibody in sample can be detected by fluorescence immunoassay assay

It is recommended that each laboratory establish its own normal range representing its patient population.
TEST RESULTS AND INTERPRETATION
- The above data is the result of HCV-Ab reagent test, and it is suggested that each laboratory should establish a range of HCV-Ab detection values suitable for the population in this region. The above results are for reference only.
- The results of this method are only applicable to the reference ranges established in this method, and there is no direct comparability with other methods.
- Other factors can also cause errors in detection results, including technical reasons, operational errors and other sample factors.
STORAGE AND STABILITY
- The kit is 18 months shelf-life from the date of manufacture. Store the unused kits at 2-30°C. DO NOT FREEZE. Do not use beyond the expiration date.
- Do not open the sealed pouch until you are ready to perform a test, and the single-use test is suggested to be used under the required environment (temperature 2-35℃, humidity 40-90%) within 60 mins as quickly as possible.
- Sample diluent is used immediately after being opened.
WARNINGS AND PRECAUTIONS
.The kit should be sealed and protected against moisture.
.All positive specimens shall be validated by other methodologies.
.All specimens shall be treated as potential pollutant.
.DO NOT use expired reagent.
.DO NOT interchange reagents among kits with different lot No..
.DO NOT reuse test cards and any disposable accessories.
.Misoperation, excessive or little sample can lead to result deviations.
.As with any assay employing mouse antibodies, the possibility exists for interference by human anti-mouse antibodies (HAMA) in the specimen. Specimens from patients who have received preparations of monoclonal antibodies for diagnosis or therapy may contain HAMA. Such specimens may cause false positive or false negative results.
